J. S; CLARK DISPENSER FOR COLLAPSIBLE TUBES HAVING A SLOTTED ROLLER ANDA ROUNDED EDGE COOPERATING THEREWITH filed Sept. 14, 1950 IN VEN TOR.

Patented June 23, 1953 UNITED STATES PATENT OFFICE DISPENSER FORCOLLAPSIBLE TUBES HAV- ING A SLOTTED ROLLER AND A ROUNDED EDGECQOPERATING THEREWITH 2 Claims.

My invention relates to holding and squeezing devices for paste tubes.

The principal object of my invention is to provide a device for holdingand squeezing collapsible containers carrying a substance which it isdesired to discharge through openings therein.

A further object of the invention is to provide a device which may beattached to or taken from the wall or other surface-as the need arises.

A further object of the invention is to provide a device which willsupport and squeeze a tube either suspended or in an upright position,using the same roller for either position.

A further object of the invention is to provide an attractive,inexpensive and a thoroughly practicable device.

These and further objects of the invention will be set forth in thefollowing specification, reference being had to the accompanyingdrawing, and the novel means by which said objects are effectuated willbe definitely pointed out in the claims.

Fig. 1 is a perspective view showing a tube suspended between thesqueezing mechanism.

Fig. 2 is a transverse sectional view of the invention showing a tubebeing fed through the lower squeezing mechanism.

Fig. 3 is also a transverse sectional view of the invention showing atube being fed through the top squeezing mechanism.

Fig. 4. is a front view of the invention.

Fig. 5 is a perspective view of the slotted roller.

Fig. 6 is a transverse sectional view of the short end of the roller.

Referring to the drawing, 2 indicates the housin or frame member havingtop side and end walls with a slot in the top wall, as shown in Fig. 1.The ends have apertures forming bearings for accommodating the slottedroller 5. The lower portion of the back has two or more openings forscrews to hold the body to the wall as 2 shown in Fig. 4. The slottedroller 5 has an extended trunnion on which is mounted a thumb piece! forturning the roller. When the flattened end of the tube is inserted inthe slotted roller and the thumb piece 1 turned the tube is drawnbetween the squeezing mechanisms as in Figs. 2 and 3. The flanges 8 and9 forming rounded edges at the side of the slot and at the edge of oneside wall, respectively, of the frame member as shown in Figs. 2 and 3are rolled sui'ficiently to allow the tube in to pass yet retarding thetube sufficiently to cause it to wrap tightly around the pulling rollerwhich causes a pressure on the tube and roller which forces out thecontents.

."iclaim:

1. Means for supporting and compressing a collapsible tube, comprisin ahousing having top, side and end walls, and open at the bottom, each endwall having a bearing, a slotted roller journaled in said bearings, thetop wall having a slot with a rounded edge at one side of said slot, andone of the side walls having a rounded edge, whereby a collapsible tubemay be inserted either upwardly through the open bottom, or downwardthrough said slot into the slotted roller, the rounded edges cooperatingwith the roller to expel the contents from the tube.

2. A device as claimed in claim 1 in which one side wall has meansiorattachment to a support.
